Question 1: No, the China-Australia Double Class is a joint project of business schools and Australian universities. It is independent, you must apply for USQ to study, otherwise you will only study general management in ZUCC's business school.
Question 2: Yes, but if you complete USQ, that is, double classes, you can get an Australian diploma. In other words, if you study USQ in China, you can get two diplomas from Australia and City College. But if you want to study in Australia, it's convenient.
Question 3: Yes.
This school is quite good. Although there are three books, no two grades can't get in. There is also 1 book, which has a strong interpersonal network and is worth collecting.
